Background and purpose: Mitigation of intrafraction motion (IM) is valuable in stereotactic radiotherapy (SRT) radiotherapy where submillimeter accuracy is desired. The purpose of this study was to investigate the application of triggered kilovoltage (kV) imaging for spine SRT patients with hardware by correlating kV imaging with patient motion and summarizing implications of toleranc... https://www.roneverhart.com/POISON-OPEN-UP-AND-SAY-AHH-T-SHIRT/
